It isobvious that the switch may be moved by some other part of this systemof rods and levers. Thus it may be on the rocking shaft 1.

Our improvement in the arrangement of the magnets in machines of thiskind, whether they be for controlling the perforator, the

justifier, or the matrix-selecting mechanism, is illustrated in Figs. 2,3, and 4. In order to retain the efficient horseshoe magnet, whilesaving the room occupied by two bobbins, the magnet is constructed withtwo cores, only one of which is wound, the other being attached to thesame anchor-plate as the wound core, so that it is in the same magneticcircuit. At the same time this bare core forms the support for thearmature-lever, which is also of magnetically-susceptible material.

In Fig. 2, g and g are the soft-iron cores, g the anchor-plate, and gthe bobbin of fine wire. The soft-iron armature-lever '2; is pivoted tothe bare core g, so that a short and well-closed magnetic circuit isobtained. Since the core can be brought very close to the bobbin 9 thefulcrum of the lever 01 can be close to the armature, leaving a long armwith a considerable striking distance to lift the stop or perforator oof the particular part of the machine which the magnet is operating andalso allowing the armature to be very close to the core 9. The spring '0is attached to a pin '0 in the anchor plate 9 The latter is rounded atthe inner end, as shown in Fig. 4:, and several of them are placed asradii of a circle or are of a circle on the magnet-stand h. The wiresfrom each magnet are brought down through a hole in the stand, linedwith insulating material it, to a central terminal plate 7L Having thusdescribed the nature of this invention and the best means we know ofcarrying the same into practical effect, we claim 1. In a perforatormechanism for preparing the composing-strip of atype setting and castingmachine in which a composing type-writer is used for closing themagnetic circuit of a perforator, the combination with the key thatreleases the counting mechanism of such typewriter to permit it toreturn to zero, of an electrical switch which closes a magnetic circuitof the perforator when the said key is depressed, in such manner thatthe circuit is closed and the counting mechanism released by onemovement of the operator, substantially as described.

4. In a perforator mechanismfor preparing the composing-strip of a typesetting and casting machine, in which the movements of parts arecontrolled by electromagnets, the combination with punches or stops, ofelectromagnets each having two cores on the same anchor-plate only oneof which cores is wound to permit the magnet to be energized while theother forms the fulcrum of the armature lever, the said anchor-platebeing rounded at its interior end and a number of such plates beingarranged as radii of a circular arc, substantially as described.
